需要比较享乐尺度和恰到好处（Just-about-right）尺度，因为先前使用享乐尺度的研究数据表明，预测的最佳成分水平通常与目前成功销售的产品中的水平不同。因此，在这项研究中，消费者测试了糖浓度从6%到14%不等的柠檬水，使用（1）由盒子或线形成的一个盒子规模和（2）一个享乐盒型规模。确定了柠檬水的预测“最佳”甜度水平和对制剂的喜好差异。线标度和箱标度给出了类似的预测最佳结果（分别为9.2%和9.4%蔗糖），其显著低于享乐标度结果（10.3%蔗糖）。在偏好测试中，消费者明显喜欢10.3%的柠檬水，而不是9.3%的浓度，这表明，基于配对偏好测试，享乐尺度比享乐尺度更好地预测了最佳甜度。
A comparison of hedonic scales and just-about-right (JAR) scales is needed because data in previous studies using JAR scales suggest that predicted optimum levels of ingredients often are not the same as the levels in products that currently are sold successfully. Thus, in this research, consumers tested lemonade varying in sugar concentration from 6% to 14%, using (1) a JAR scale formed by boxes or a line and (2) a hedonic box-type scale. Predicted "optimum" levels of sweetness for the lemonade and differences in liking for the formulations were determined, The JAR line and box scales gave similar predicted optimal results (9.2% and 9.4% sucrose, respectively), which were significantly lower than the hedonic scale results (10.3% sucrose). In a preference test, consumers significantly preferred the 10.3% sugar lemonade over the 9.3% concentration, indicating that, based on paired preference testing, the hedonic scale resulted in better prediction of optimal sweetness than the JAR scale.
